On this one, I decided to go through the front-end, and then the back-end. Here, I am stripping the front
After removing all the frame
panels, I stand the unit up
on end. The controls hang
loose. Panels and front half
of the frame are washed.
Each of the front-end
boards will be examined,
cleaned, and receive a new
set of caps.
These are sealed units. I used my micro drill to drill a
small hole in the corner of each switch. These can be
resealed after cleaning, with a small amount of gap
filling CA glue if desired.
This allows the DeoxIt applicator to reach across to
both contact rails. I was able to place a drop on each
Note the burned resistor in the upper right corner.
This is a metal oxide resistor. They use this type
because they can take a lot of heat... and have good
tone qualities. The resistor was still functional, but I
replace any suspect components. The replacement
resistor is also metal oxide (sometimes called "flame
proof resistor"). It is the modern equivalent.
You can see them installed on the finished board.
